The next ANNUAL GENERAL MEETING will be held at YORK,

Notice to Contributors of Memoirs. — Authors are reminded that, under an 

 arrangement dating from 1871, the acceptance of Memoirs, and the days on which 

 they are to be read, are now, as far as possible, determined by Organizing Commit- 

 tees for the several Sections before the beginning of the Meeting. It has therefore 

 become necessary, in order to give an opportunity to the Committees of doing 

 justice to the several Communications, that each Author should prepare before- 

 hand an Abstract of his Memoir, of a length suitable for insertion in the pub- 

 lished Transactions of the Association, and the Council request that he will send 

 it, together with the original Memoir, by book-post, on or before August 1, 

 addressed thus : — " General Secretaries, British Association, 22 Albemarle Street, 



London, W. For Section " Authors who comply with this request, 



and whose Papers are accepted, will be furnished before the Meeting with printed 

 copies of their Reports or Abstracts. If it should be inconvenient to the Author 

 that his Paper should be read on any particular days, he is requested to send 

 information thereof to the Secretaries in a separate note. 



Reports on the Progress of Science, and of Researches entrusted to Individuals 

 or Committees, must be forwarded to the General Secretaries, for presenta- 

 tion to the Organizing Committees, accompanied by a statement whether the 

 Author will be present at the Annual Meeting. 



No Report, Paper, or Abstract can be inserted in the Report of the Associa- 

 tion unless it is given in before the conclusion of the Meeting. 



G. GRIFFITH, 



Acting Secretary.
